NONREFILLABLE BOTTLE.

Specification of Letters Patent. Patented Jan. 17, 1922.

Application filed June 1, 1920. Serial No. 385,757.

To all whom it may concern:

Be it known that I, WILLIAM RICHARD GIBsoN, a subject of the King of Great Britain, and a resident of Sittmgbourne, in the county of Kent, England, have invented certain new and useful Improvements in Nonrefillable Bottles, of which the following is a specification.

This invention relates to nonrefillable bottles and has-for its object to provide a device for application to bottles by means of which while freedom for emptying the bottle is provided for, the refilling of the bottle is positively prevented.

The invention consists broadly of a nonrefillable bottle provided with a bulb or cap adapted to be sealed over the neck of the bottle and provided with a pouring outlet; In this bulb or cap is arranged a short length of flexible tubing leading from the interior of the bottle and adapted to permit the free flow of liquid from the bottle but operating to prevent the introduction of liquid into the bottle.

In the preferred form of this nonrefillable bottle the neck extends into the said bulb or cap and on this extending portion of the neck is fitted one end of a flexible tube the other end of the tube being weighted so that it will fall over the rim of the neck in such a manner as to hold the sides of the flexible tube together and so close it. Any liquid introduced through the pouring out let of the bulb or cap will also tend to press the sides of the said tube together and so prevent the refilling of the bottle.

The bulb or cup is preferably provided with one or more perforated partitions or diaphragms extending across it between the pouring outlet and the neck, the perforations being inclined in such a manner as to deflect a. wire or the like introduced through the said outlet for the purpose of endeavoring to perforate or remove the flexible tube.

' For the same purpose, when the bulb or cap is provided with more than one partition, the perforations in one of them are arranged out of line with those in the next partition.

The bulb or cap may be fixed on the bottle by a screwed joint or by any suitable connection adapted to be sealed, and its pouring outlet may be provided with a cork or stopper.

In the invention as illustrated in the acoutwardly companying drawing, a, is a bottle having a screwed portion a on which is adapted to fit the internally screwed neck of the bulb or cap I). The rimmed neck 0 of the bottle extends into the bulb b, and on this neck portion is fitted one end of a flexible tube d, the other end of this tube being provided with a tube d preferably of glass and provided with a protecting rubber rim d The tube (Z forms the weighted end of the flexible tube d. b is a washer of cork or other suitable material. is a partition or diaphragm having a number of inclined perforations 6 6 formed near the walls of the bulb. b is a pouring outlet.

What I claim and desire to secure by Letters Patent is A nonrefillable bottle comprising a hollow body, a reduced exteriorly threaded neck on the upper end of said body, a further reduced neck projecting from the upper end of said screwed neck having a peripheral head or flange around the top edge of the same, an aperture extending centrally through said beaded neck communieating with the interior of the bottle body, a short length of rubber tube embracing said beaded neck, a rigid tube inserted within the outer open end of said rubber tube adapted to keep such end open and to operate as a weight to cause said rubber tube to fall over the side of the beaded neck and thereby hold the sides of the rubber tube together, a hollow one piece bulb or cap having a reduced lower end provided with an internally threaded opening adapted to engage the screwed neck of the bottle, a small pouring outlet at the upper end of said blub or cap, a transverse diaphragm formed integral with and extending across the interior of said. bulb or cap having a plurality of inclined apertures disposed around and adjacent to the edge of the same so as to be out of line with the pouring aperture in the cap or bulb and an annular washer interposed between the opposing faces of the cap or bulb and the lJOdY of the bottle so as to constitute a fluid tight joint therebetween when said cap or bulb is screwed tightly home, substantially as specified.

In witness whereof I afiix my signature.

WILLIAM RICHARD GIBSON.
